county of Kings, and State of New York,

have invented a certain new and useful lm` provement `in Rowing-Boats,of `which thej` following is a full, clear, and exact .specification. u

f This invention relates more particularly to a class of boats.` I `Myinvention has .for its object primarily, to provide a rowing boatwhereby a person who may be unskilled or skilled in the art of rowingmay convenientlyr operate the y oars for propelling the boat, and whichis of a form so that the oars will be prevented from becomingaccidentally displaced froml the hull ofthe boat to avoid being lost especially when the water isrough. The invention consists essentially of ahulljwith `oars fulcrumed at opposite parts of its sides so as tobemoved rotatably as wellas back- Y wardly and forwardly, and theoarsare con-` nected by an operating bar` so that when swung backwardly`the oars willbe partially rotated to cause their blades to Isimul-`taneously out the water and when swung 1 -baokwardly thefoars will bereverselyro-m tated to take the pressure of the water. n

A Other objects of the invention are `to prol vide elements whichconnect the operating` bar to the oars so that the bar will be adjust-1able to allow the boat to be rowed backwardly as Well as forwardly; andto provide retainers for holding the oars tolthe hull against accidentaldisplacement.` t

A practical embodiment of the invention is represented 1n theaccompanying drawing forming apart of this specificationin which similarcharacters of reference indicate corresponding parts in all the views,and will then be pointed out in the claims at the end of thedescription.

In the drawing, Figurel isa top, planof one form of rowing boatembodying my `1nvention. t

Fig. 2 is a side elevation of the boat. Fig. 3 is aV fragmentary viewshowing a top plan of one of the elements foradjust-` ing the oars ofthe boat as well as `one end .of the operating bar connectedthereto, andFig. 4 is a fragmentary View, showing a of rowing a boat.

The .beat has a hun 1o which` may be of anysuitable shape and sizehaving a round,

Each` of these retainershas a5 sleeve A18 through thepassagefof` each of which is `lnovaloly guided the upper part of the bar.15 of each of the oars so that thejupper ends of the bars will extendsome distance above the sleeves, and these sleeves are formed "with`substantially semi-circular pe` ripheries. The sleeves 18 are arrangedso that their straight edges"` abut against the sides of the hull y, ofthe boat, and each of u these sleeves ispivoted`,;at 19, to plate 2() onthefsideiof` thehulllO to allow the sleeve to beswungas well `as-theoarbackwardly and forwardly'toward and from thebow of the boatand viceversa",` The sleevesare arranged so that their upper portions extendabove the hull ofthe boat, and on the top of each sleeve is astationaryplate` 21, and

both `tofV these plates may be approximately oval in shapes of larger"diameters than the f sleeves aswell as being arranged whereby opposedparts thereof overhangtheinterior of the hull 10.` The part of each barlof the oars adjacent to the lower end of its sleeve` is movably guidedthrough an elongated fstrap22 provided on the platefZO of,`
